I agree with your thought, but often times the judicial system needs to get involved to determine if someone's rights were violated. Civil action can be the trigger (no pun intended) to put the wheels in motion to determine if a cop needs disciplinary action against him or just an education of the law. Without the civil action, an investigation and corrective action would most likely never occur.
If it wasn't a shakedown and pay off, was there a written apology? A reprimand? An investigation? Will these same officers, if they acted improperly, act again the same way on the next check lane? Will the next person know their rights? Has it happened before? Who will know now?
More facts needed but not, apparently, on this thread for some Code Orange Freepers.
But thank you for your thoughtful, rational reply.
